. 2(3lainis. 1 {This invention relatesto an-improvedconestruction of game balltable which is constructed and arranged to be played in simulation ofthe well known game of pool, and more particularly constitutes an improvement on my prior application for. U. S. Letters Patent, entitled Mechanical Pool Table, filed July 19, 1944, and bearing Serial Number 545,583, now Patent 2,450,613, issued on October 5,1948.

Whereas in my prior application, each ball after being played is returned'either by way of one of the pockets or by a return gate to a locked position beneath the table or playing surface, the present invention permits of the retention onathe table, until the completion of agame, of any balls which do not enter into a pocket of the table when initially played, so that subse quently played balls may be utilized similar to one balls in the conventional game of pool, for driving theballs remaining on the table into the table pockets, thus increasing the score capable of being obtained as a result of special skill of the player and-thus rendering the game more interesting and more'similar in'play to the conventional game of pool.

A further object of the invention is to provide an improved construction of: game table possessing the characteristicsheretofore descrimd and which is provided with mechanical means; for returning all of the balls to a locked position between the completion of one game and the commencement of .another. v Various other objects and advantages of the invention will hereinafter become more fully apparent, from the following description of the drawing; which illustrates'a preferred embodiment thereof, and whereinv Figure 1 is a perspective view of the improved table; I

' As. the present, invention relates only to improvements in the table topor playing surface as Application September 1 covered by my. prior application for patent, pre- "viously referred to, only so much of the mechani .is illustrated in Figures 1 and 2 and includes a pair of side walls8 and 9 and an outer endpor tion- H3. The end portion I'll includes an upwardly; facing glass panel or pane H, through which an electrically actuated score board, not shown; ,will be visible. Inwardly of the transparent panel H, theend portion in is provided .withan arcuate-cushion.!.2, which is concave and which isgprovided with two pocketrecesses 13,

whichare located above arcuate recesses Hi which are formed-in-thebottom; ofthe inner edge of the table partill,

The playing table I or surface-proper, designated generally l5 is-provided with anarcuate convex edge 1'6 at its outer end, which is'located adjacent and beneath the concave cushion i2 and which is provided withindentations or recesses ll. which register with the recesses 14 to form openings, and which in conjunction with the cushion recesses [3 form :ball receiving pockets. 7 ,1 The table or surface l5 is pivotally'mounted adjacent its outer edgelfi on a pair of laterally aligned pivots I8. I As best seen in Figure 5, each pivot l8 includes a headed pin l 8 having a smooth shank portion which is turnably engaged by a loop or barrel portion 2!! formed on one end of a plate' 2l;.- The pivot pins 59 are provided with opposite tapered threaded ends 22 which are anchored in the frame sides 8 and 9 in a manner to-cause the pivot pins {'9 to project inwardly therefrom. The plates .2l are connected by fastenings .to..--the--un derside of the table or surface 15,: andjadjacent the side edges thereof, to combine with the anchored pivot pins IQ, for pivotally mounting the table or surface l5 near its'outer end.

The surface I5 is :provided with a restricted opposite end having corresponding upstanding side walls 23 whichextend to the ends of a concave inner end portion 24 and which converge towardsaid portion. Portion 24 defines a part of ;a gate; or,I ball receiver, for apurpose which will hereinafterbecome-apparent. The side walls 23 form integral extensions of the integralupstandingand parallelside walls 25 of ,surfaceil5 3 which extend from the walls 23 to points adjacent the pivots l8 and which are provided with inwardly extending resilient cushions 26. The cushionsldare each provided with a recess 21 around an opening 28 in the surface 15. re-

cesses 27 and openings 28 combine to form additional ball receiving pockets. The cushions 26; at their outer ends are provided with beveled.

surfaces 29 for exposing additional openings38 in the table l5 and which combine therewith toll form two additional ball receiving pockets. It

will be noted that the poe'ket's zfoiniedby the recesses I 3 and openings l4, l'l, recesses 21' and. openings 28, and beveled surfaces 29 and openmy prior application for patent, previously referred to. With the shaft 3| in its position of Figure 1 and Figure 3, the table or playing surface l5 will be substantially in a horizontal position, so that the balls 52cmay be accurately propelled thereon toward the various pockets, previously described. Any balls 52 failing to enter a pocket, when initially driven by the spring loaded cue will in most instances, after bounding Op offone or more of the cushions l2 and/or 26 "come to rest on the horizontal surface I5. Subsequently propelled balls 52 can then be utilized in a manner similar to a cue ball for attempting to"po'cket the balls remaining on the surface l5,
